Abstract: Ame en nid d'abeilles constituée de bandes d'un matériau tel que la cellulose dont la résistance et/ou la forme varient en fonction de l'humidité. Lesdites bandes sont disposées en couches parmi lesquelles se trouve une couche de plastique qui peut être placée entre deux couches du matériau hydrosensible ou leur être intégrée. On peut donc ainsi former un panneau de nid d'abeille à construction en sandwich dont l'âme est en nid d'abeille et dont les plaques de couverture, collées à l'âme, sont faites du susdit matériau en cellulose, dont la résistance et/ou la forme sont sensibles à l'humidité lesdites joues formant des faces de panneau, au moins une desdites joues étant étanche à l'humidité. L'une au moins des plaques de couverture peut consister en plusieurs couches, dont une en plastique. La plaque de couverture concernée peut comprendre deux couches du matériau hydrosensible, la couche de plastique se trouvant entre elles ou leur étant intégrée.

Title: Retrievable milling guide anchor apparatus and associated methods
Inventor: WHITE PAT M
IPC: E21B7/08
Filed: 1997-12-04
Abstract: In a parent wellbore casing, full bore access to the portion of the casing beneath a lateral bore liner portion therein is provided using a specially designed tubular retrievable anchor assembly hydraulically set within the casing above the liner portion and having a depending mill guide portion. A milling pipe with a first rotary mill is extended through the anchor assembly, with the mill being laterally deflected by the guide to mill a partial opening through the bottom side wall of the liner portion. The milling pipe is then withdrawn from the casing, the first mill replaced with a second rotary mill, and a specially designed tubular retrieval collet coaxially secured to the milling pipe. The milling pipe is then extended downwardly through the anchor assembly, the second mill used to enlarge the initial liner opening, and the collet snapped into the anchor assembly. The anchor assembly is then retrieved by pulling up on the milling pipe to release the anchor assembly which is removed from the casing. A full bore mill, having an elongated nose portion guidingly receivable in the partial liner hole, is then lowered into the casing and used to bore out the liner portion within the casing to provide full bore access to the parent casing portion beneath the previous location of the lateral bore liner portion therein.

Abstract: The disclosure relates to an apparatus and a method for producing a hose package (1), formed by folding of a hose (2) of flexible material, in which the hose package consists of folds joining one another and composed of wall elements formed in the folding and contiguous with one another. These are located outside one another in relation to a centre axis (24a) of the hose package. A fixing device (10a), a lower folding device (11) and an upper folding device (12) formed as polygons form, by a controlled sequence of movements, the folds and thereby the hose package. The lower folding device is disposed, on braking of the folding cycle, to stop in its position located most distal from the centre axis (24) of the apparatus when a predetermined quantity of hose has been accumulated in the hose package. As a result, the hose package is fixed and a cutting device (36) which is provided for cutting the hose separates the hose package from the hose in a region above the hose package.

Title: Transit vehicle door system
Inventor: BOWEN SCOTT N
IPC: B60N5/00
Filed: 1998-10-05
Abstract: The invention provides a door system for a transit vehicle. It has an actuator which provides a rotary motion about an axis of the actuator for moving the door panel between an open position uncovering the aperture and a closed unlocked position covering the aperture. The actuator also provides a linear motion along the axis of the actuator for moving the door panel between the closed unlocked position and a closed locked position. The rotary motion followed by the axial motion is provided by a cylinder having a piston moved by fluid pressure. The piston includes a guide track in its exterior which engages rollers in the cylinder. The guide track has one portion curving around the piston and one portion parallel to the axis. The curving part provides the rotary motion and the straight part provides the axial motion. When the rotary motion is completed the piston encounters a stop on a shaft which supports the door. The actuator then moves the door axially to engage locks.
